Bootstrap4 加载效果
要创建加载中效果可以使用 .spinner-border 类:
实例
<div class="spinner-border"></div>
可以使用文本颜色类设置不同的颜色：
实例
<div class="spinner-border text-muted"></div> <div class="spinner-border text-primary"></div> <div class="spinner-border text-success"></div> <div class="spinner-border text-info"></div> <div class="spinner-border text-warning"></div> <div class="spinner-border text-danger"></div> <div class="spinner-border text-secondary"></div> <div class="spinner-border text-dark"></div> <div class="spinner-border text-light"></div>
闪烁的加载效果
使用 .spinner-grow 类来设置闪烁的加载效果:
实例
<div class="spinner-grow text-muted"></div> <div class="spinner-grow text-primary"></div> <div class="spinner-grow text-success"></div> <div class="spinner-grow text-info"></div> <div class="spinner-grow text-warning"></div> <div class="spinner-grow text-danger"></div> <div class="spinner-grow text-secondary"></div> <div class="spinner-grow text-dark"></div> <div class="spinner-grow text-light"></div>
设置加载效果大小
使用.spinner-border-sm 或 .spinner-grow-sm 类来创建加载效果的大小:
实例
<div class="spinner-grow text-muted"></div> <div class="spinner-grow text-primary"></div> <div class="spinner-grow text-success"></div> <div class="spinner-grow text-info"></div> <div class="spinner-grow text-warning"></div> <div class="spinner-grow text-danger"></div> <div class="spinner-grow text-secondary"></div> <div class="spinner-grow text-dark"></div> <div class="spinner-grow text-light"></div>
加载按钮
我们也可以设置一个正在加载的按钮。
实例
<button class="btn btn-primary"> <span class="spinner-border spinner-border-sm"></span> </button> <button class="btn btn-primary"> <span class="spinner-border spinner-border-sm"></span> Loading.. </button> <button class="btn btn-primary" disabled> <span class="spinner-border spinner-border-sm"></span> Loading.. </button> <button class="btn btn-primary" disabled> <span class="spinner-grow spinner-grow-sm"></span> Loading.. </button>
